1.Reasonable stnrctural design, good rigidity and goodsealmg performance. 2. In the course of open and close, nearly no abrasion is between the valve flap and valve suit. So, it is wearable. 3. Small open height can reality the flux. 4. Can be installed in any position of pipeline. 5. The filling adopts soft graphite, which can reach flexible open and dose and reliable sealing. 6. Large diameter manual valve is equipped with bump hand wheel. 7. Be widely cscd in the pipeline of water, vapor and oil prodtcts of petroleum, chemical indistry, thermal power for connection and dam media. To change the valve flap shape can throttle for systematic media.
